Today a tried to built a rootfs on an i386 platform for an lxc container
(so we have the same architectures on both sides).

The configuration is done automatically right after unpacking. But I
like to reuse my tested Makefile snippets [1], which already took care
of bind mounting /proc etc in the targetfs, so the configuration for
packages which need those won't fail.

Is there a way to swich the configuration step off in native mode (I'm
using mutlitrap from stable-backports.)?
